Barnacle will act like a wireless router connecting its clients to the
Internet via the phone's 3G (or 2G) mobile connection.

Supported hardware

Barnacle Wifi Tether is compatible with Windows (XP/Vista/7), Mac, Linux, even
iPod/iPhone/iPad and Xbox! If you are having more trouble connecting to some
devices than others, it's recommended to use this association
technique.

On many phones you need to enable Skip
wpa_supplicant in Settings to actually create the
ad-hoc network. In that case WEP will most likely not work.
